LEAF-TURNING APPARATUS FOR BOOKS, MUSIC, 81.0.

' Specification of Letters Patent.

Patented Aug. 7, 1906.

Application filed August 19,1905- SBTiRl 274,902.

To all whu'm it may concern.-

Be it known that I, LEONARD GILBERT GILES, a subject of His Majesty theKing of Great Britain, and a resident of 24 Eastern street, Aylesbury,county of Buckingham, England, have invented certain new and use fulImprovements in Leaf-Turning Apparatus for Books,Music, and the Like,(for which I have made application for patent in Great Britain, No.1,742, dated January 28, 1905,) of which the following is aspecification.

This invention relates to an improved construction of apparatus forturning over the leaves of books, music, and the like.

In the accompanying sheet of drawings I have illustrated and willdescribe with reference thereto a form of construction which I havefound to work well.

Of the drawings, Figure 1 is a front eleva tion of the apparatus. Fig. 2is a sectional side view taken upon the line 00 cc of Fig. 1.

Fig. 3 is an end view of the apparatus as shown by Fig. 1. Fig. 4 is aview similar to Fig. 2, illustrating a slight variation of arranging thereleasing mechanism. Fig. 5 is a like view to Fig. 4, but showing partsin another position, while Fig. 6 is a detail view to be hereinafterreferred to.

In carrying my invention into effect I stamp or otherwise produce fromsheet metal or other suitable material a frame consisting of an upperplatform a and a lower platform I), connected together by a back piece0, which may have portions (1 out out and turned over, as shown in Figs.1 and 3, to provide a back rest at the rear of the upper platform a. Thelower platform b has connected to downwardly-projecting portions ethereof hinged clamps or like fastening means f, which, in conjunctionwith thumb-screws or the like g, are adapted for securing the apparatusto a music desk, stand, or the like.

The right-hand end of the frame a b c is suitably provided with a sidepiece h, and adjacent to the platforms is pivotally connected the oneend of a spring-controlled lever i, having a stud working in a slide iand carrying a pair of stops, pins, projections, or members j and 76 ofunequal length. If the lever 'i be pivoted to a lug beneath the lowerplatform I), such pins or stops may work through the latter; but inpractice I prefer to pivot the lever, as shown, to the side h andarrange the pins or members j and 7c to work through an inturned piece,flange, or plate Z of such side h and at either side of a stop orprojection m.

Preferably centrally of the platforms a b is secured a spindle n, onwhich are mounted so as to be located between the platforms, a number ofcollars 0, each having secured thereto a wire or rod p, carrying at itsfree end an adjustable spring-clip device y of suitable construction.Each of the wires or rods is independently controlled by means of acoiled spring 9, arranged round a reduced part of the collar 0 andconnected at one'end to the latter and at the other end to a rod 7',substantially as shown at'Figs. 1 and 6.

Before release of the Wires the free ends thereof are arranged toproject through a guide-slot 8', formed, as shown, in the end h, andadjacent to the stops j la a recess tis pro,- vided to permit the wiresin turn to be delivered over the shorter stop of the operating-lever ito and behind the longer stop 7; thereof, as shown in Figs. 2 and 3. r

The before-mentioned spindle n is'for preference formed hollow or partlyhollow for receiving in removable connection therewith a rod 41) for themusic or the like to go round, and for use with loose sheets of music arod 4), having an adjustable clip w thereon for holding such loosesheets may be arranged to be fitted onto said rod aand adjusted by thescrew as, as shown in Fig. 1.

As a slight modification of the foregoing I may dispense with one of thepins j k, as shown by Figs. 4 and 5. In this embodiment of my inventionI provide a lever, such as 1, and pivot it at 2 to the side h andconnect at its inner end a pin 3, reduced in size at its upper part forworking through the inturned piece I just in front of a stop 4, situatedat the fore end of the guide-slot s, so thatthe wires or rods p must befirst raised over such stop 4 before they can be released. The lever 1is normally kept in the position shown in Fig. 4 by the spring 5, but onthe free end being depressed, as shown in Fig. 5, the pin 3 raises oneof the wires p clear of-the stop 4.

In use the clip devices 1 on the wires or rods p are respectivelyarranged to grip the leaves in proper order, and each time theoperating-lever is depressed one of the wires or rods p is released andby the force of its spring (1 turns over the leaf connected to its clip.In the arrangement shown by Figs. 2 and 3 the depression of the leverbrings both pins to the level of Z and allows the wire behind the longerpin to be carried over. During this operation the next following wirehas impinged against the stop m and is above the shorter pin, which onthe return movement of the lever i by the spring 2 raises the wire abovem and delivers it to and behind the longer pin, ready to be releasedwhen the. lever is again depressed. In the arrangement shown by Figs. 4and 5 each wire is directly raised above the stop 4 and released, ashereinbefore stated.

In lieu of arranging the vertical parts at to form a back rest I may insome cases provide a movable back rest arranged in any wellknown way tobe fixed substantially horizontal or substantially vertical, accordingas a large music-book or an ordinary single piece Of music, for example,is to be used therewith.

Having now described my invention, what I desire to secure by LettersPatentis 1. A leaf-turning apparatus comprising a frame, a number ofspring-controlled arms pivoted thereto, a stationary stop on the framefor holding said arms in their inoperative position, and means forreleasing the arms from the stop, said means consisting of aspring-controlled operatinglever pivoted to the frame and a fingerpivoted to the lever and working adjacent to the stop.

2. A leaf-turning apparatus comprising a frame, a number ofspring-controlled arms pivoted thereto, a stationary stop on the framefor holding said arms against the action of the springs and means forreleasing said arms from the stop, said means consisting of a leverhaving one end pivoted to the frame and a long and a short finger onsaid lever arranged on opposite sides of the stop, the short finger onthe upward stroke of the lever raising one arm over the stop and thelong fmger catching and holding said arm until the lever is depressed.

8. An apparatus for turning the leaves comprising a pair of connectedplatforms adapted to be secured to a music-stand, a spindle locatedbetween said platforms, a number of spring-controlled collars looselymounted on the spindle, an arm connected to each of said collars, aguide-slot located at one end of said platforms, a stationary stoptherein for holding the arms against the tension ofthe springs, aspring-controlled operating-lever and a pair of members pivoted theretofor releasing the arms one by one from the stop, substantially asdescribed.

In witness whereof I have hereunto set, my hand in presence of twowitnesses.
